Embroidery machine tension problems are just plain frustrating. One moment your stitches look perfect, and the next… loops, tight threads, or bobbin showing on top. Sound familiar? Don’t worry, you’re not alone, and the good news is, you can fix most tension issues yourself without calling a technician.
How to Fix Embroidery Machine Tension Problems in 5 Simple Steps?
In this guide, I’ll walk you through 5 super practical steps to fix embroidery tension problems at home:
- Rethread Your Embroidery Machine
- Adjust the Top Thread Tension Dial
- Check and Adjust Bobbin Tension
- Clean the Tension Discs and Remove Debris
- Test Stitching on Similar Fabric and Fine-Tune
These aren’t just random tips, they’re the exact steps experienced embroiderers use every day to get smooth, clean stitches. So grab a test fabric and let’s get that machine running right again!
Step 1: Rethread Your Embroidery Machine
Let’s start with the most common fix, rethreading your embroidery machine. You might be surprised how often tension issues are caused by something as simple as incorrect threading.
First, completely remove both the top thread and the bobbin thread. Don’t just pull them out, cut them at the top and pull gently from the needle area to avoid dragging lint into the tension discs.
Now, take a moment to rethread your machine from scratch, following the guide that came with it.
Make sure the thread passes through every guide, tension disc, and especially under the tension knob. This is where many users go wrong, if the thread skips even one guide or isn’t firmly seated, it can throw off your stitch tension completely.
Incorrect threading is one of the main reasons why people struggle with embroidery machine tension, so don’t skip this step, even if you’re sure you did it right before.
Step 2: Adjust the Top Thread Tension Dial
Once your machine is threaded correctly, it’s time to check the top thread tension dial. You’ll usually find it on the front or side of your embroidery machine.
Here’s how it works: turn the dial clockwise to increase the tension, and counterclockwise to loosen it.
After each small adjustment, don’t guess, run a quick test stitch on a piece of scrap fabric that’s similar to your actual project.
You want to look for even, balanced stitches, the threads should interlock neatly inside the fabric without visible loops on either side.
If you’re noticing bobbin thread showing on top, it could mean your top tension is too tight. If the top thread is loose and looping on the back, you’ll need to tighten it slightly.
Remember, small changes matter. Adjust in tiny steps and test again until the stitch quality looks right. This hands-on approach is the key to mastering tension on embroidery machine settings.
Step 3: Check and Adjust Bobbin Tension
Now let’s focus on the bobbin tension, which often gets overlooked. Remove the bobbin case and test the tension using a bobbin tension gauge, if you have one. If not, here’s a trick: pull the thread gently. It should offer slight resistance, not too tight, not too loose.
To adjust, find the tiny screw on the side of the bobbin case.
Turn it clockwise to tighten, or counterclockwise to loosen, always in very small increments, no more than a quarter turn at a time.
After adjusting, insert the bobbin case back into the machine and sew a few stitches on your test fabric. This will help you evaluate how well the bobbin thread is balancing with the top thread.
And don’t forget to clean the bobbin area regularly. Lint buildup can interfere with proper tension, causing random issues that drive you crazy. Keeping this area clean is a big part of consistent machine embroidery tension.
Step 4: Clean the Tension Discs and Remove Debris
Still facing tension issues? It might be time for a cleanup.
Turn off your machine and grab a small lint brush or sewing machine cleaning kit. Focus on cleaning the tension discs, where thread passes through on its way to the needle. Also, check the bobbin case, the feed dogs, and surrounding areas for any thread scraps, dust, or lint.
Over time, debris builds up and prevents your thread from moving smoothly.
This can lead to inconsistent tension, skipped stitches, or fabric puckering, none of which you want when you’re in the middle of a project.
This part may feel boring, but trust me, a clean machine runs better. It also makes your adjustments more effective, as you’re not fighting against hidden friction. If you want a visual reference, try keeping a simple embroidery tension chart handy to understand how cleanliness affects tension.
Step 5: Test Stitching and Fine-Tune
Now that everything’s clean and adjusted, it’s time to put your machine to the test.
Grab a piece of scrap fabric that matches your project material as closely as possible. Do a quick embroidery test run and examine both sides of the stitch.
Here’s what you’re looking for: no loops of the top thread on the underside, no bobbin thread popping up on the surface, and flat, clean stitches with no puckering.
If anything still looks off, don’t worry. Just make small adjustments to the top or bobbin tension, then test again. Repeat until the stitches are balanced and the fabric looks smooth.
This final test is how you lock in the perfect settings. Keep a log or screenshot of the results if needed, some people even print their own embroidery tension guide to use across projects. You can use this chart also:
Embroidery Tension Chart
Stitch Problem | Likely Cause | Fix / Adjustment |
Top thread looping on the back | Top tension too loose | Tighten the top tension dial slightly |
Bobbin thread showing on top | Top tension too tight | Loosen the top tension dial slightly |
Uneven stitches or gaps | Incorrect bobbin tension | Adjust bobbin screw gently for proper resistance |
Thread breaking frequently | Tension too tight or poor threading | Check threading, reduce tension, and use quality thread |
Fabric puckering | Tension too tight or hoop too tight | Loosen tension or hoop, and stabilize fabric properly |
Flat and balanced stitches | Correct top and bobbin tension | No change needed—you’re good to go! |
Bonus Tips: Using a Thread Stand and Maintaining Your Machine
Once you’ve solved the main tension issues, a few extra steps can make sure your embroidery stays smooth and hassle-free. Here are some simple but powerful tips to maintain your machine tension long-term:
- Use a Thread Stand: It helps thread unwind smoothly, reduces drag and tangles, especially with large cones or metallic threads.
- Choose Quality Needles and Threads: Low-quality materials can lead to uneven stitching and tension problems. Always match the needle size to your fabric and design, and use trusted thread brands.
- Keep Your Bobbin Area Clean: Lint buildup around the bobbin can affect tension over time. Clean it regularly to avoid unexpected issues.
- Service Your Machine Occasionally: If you’ve tried everything and still face problems, have your machine checked by a professional. Worn-out springs or sensors might need adjustment.
- Use a Test Stitch Chart: Keep a small sample chart handy when switching fabrics, so you can quickly identify and fix tension issues before starting your main project.
These bonus tips are simple habits that go a long way toward keeping your machine embroidery tension consistent and frustration-free.
Conclusion
By now, you’ve learned exactly how to deal with embroidery machine tension problems in a clear and simple way. We started by rethreading the machine, moved on to adjusting the top thread tension, then checked and corrected the bobbin tension. After that, we focused on cleaning the tension discs and finally tested the stitches and fine-tuned the results.
These steps may seem basic, but they are powerful when done properly. They can save you time, thread, and fabric, and most importantly, help you achieve clean, balanced embroidery every time.
But even if your machine settings are perfect, your final results depend heavily on how well your design is digitized. A poorly digitized file can cause thread breaks, uneven tension, or sloppy stitching no matter how careful you are.

FAQs
Most embroidery machines work well when the top thread tension is between 2.0 and 4.0, but it can vary based on your thread type and fabric. Always start with your machine’s default and adjust slightly if needed. Do a test stitch to check results.
The best tension creates even, flat stitches with no loops on the back and no bobbin thread showing on top. There’s no one-size-fits-all setting, it depends on your fabric, thread, and design. Small adjustments and testing are key.
Use a scrap piece of fabric similar to your main project. Run a test stitch and examine both sides. If the top thread loops underneath or the bobbin thread appears on top, your tension needs adjusting. Make small changes and test again.
For regular sewing, the correct tension is usually between 3 and 5. However, it depends on the fabric thickness and thread type. The goal is to have both threads meet inside the fabric, creating balanced, smooth stitches without puckering.
